Abstract

Un tapón de elevación para elevar un electrodo de grafito incluye un cuerpo principal y un inserto acoplado a un extremo del cuerpo principal, con el inserto configurado para acoplarse a un electrodo de grafito para asegurar el enchufe de elevación al electrodo de grafito. El tapón de elevación también incluye un componente de elevación acoplado al cuerpo principal opuesto al inserto para elevar el electrodo de grafito. El inserto comprende un material no grafitado con un coeficiente de expansión térmica (CTE) similar al del grafito, de tal manera que el tapón de elevación se expande a una velocidad similar a la del electrodo de grafito cuando se calienta, con el fin de prevenir que se bloquee en una unión entre el tapón de elevación y el electrodo de grafito.
